2006 Oct. 31.80 UT: m1=11.6, Dia.=1.1′, DC=3/; 40.0cm L f/4.5 (144x); Seiichi Yoshida (Gunma, Japan) [I heard a rumor that it has been fading rapidly. So I thought it was already extremely diffuse and hard to see. But unexpectedly, it was still bright. It was still condensed. Many bright stars recorded in the GSC are faint galaxies in fact around this area. So it was difficult to determine the comet position. In the field, I could not see which star in the chart is a galaxy in fact. So, I was anxious that maybe I was observing a galaxy by mistake!? Because the comet looked much more condensed than expected, I could not be condident that I was really observing the comet, not a galaxy.]

2006 Oct. 13.42 UT: m1=11.3, Dia=6, DC=3; 25.4cm L f/4.5 (71x); David Seargent (Cowra, NSW, Australia)[Seemed a little more condensed, and was easier to see. A little enhanced through Swan Band filter].[The comet has obviously brightened quite fast, but probably not as quickly as it seems from these observations. During September, the comet was too faint to be seen at low power (lack of contrast between background sky and very diffuse coma), making it necessary to use higher magnifications. These, however, over magnified the image and resulted in too conservative estimates. No estimates were made in October using 114x, but there seemed little difference between September and October views of the comet at that power. Clearly, there is a very strong aperture/magnification effect operating here!]
2006 Oct. 12.81 UT: m1=11.7, Dia.=2′, DC=2; 20 cm SCT (133x); Juan José González (Sierra del Aramo, 1221 m, Asturias, España)[Cielo claro de montaña. Altura: 10 grados]

2006 Oct. 10.42 UT: m1=11.4, Dia=4; 25.4cm L f/4.5 (71x); David Seargent (Cowra, NSW, Australia)[Comet clear of star, and larger coma therefore visible. Also seen faintly with 25×100 binocular telescope as a very dim patch of mag 11.4, clearer through Swan Band filter]

2006 Oct. 09.40 UT: m1=12.5:, Dia.=1.4′, DC=2; 40.0cm L f/4.5 (144x); Seiichi Yoshida (Gunma, Japan)[Very low in the evening. The sky was not very clear and hard to see faint stars. But sometimes the sky became clear. Then I could see very faint stars, and a faint nebulous object, too. Maybe the comet is bright. But probably due to the thin clouds passing through the telescope field, I could not see the comet for a long time. The star chart around this area is very different between the GSC and ASAS-3. The DSS image suggests the GSC is right. So I report my observation using the GSC.]
2006 Sep. 27.44 UT: m1=[11.9; 40.0cm L f/4.5 (144x); Seiichi Yoshida (Gunma, Japan) [The comet was hidden by clouds when I observed C/2006 L2 in advance. When the comet appeared again, it was already low. They say it is extremely large and diffuse. The sky was not dark, so it was very hard to see a diffuse object.]

It was not excellent for me due to the hazy sky and the moon light. I could not see it with naked eyes. I could not see the tail. But the comet became much larger than my previous observation in early October. The central condensation is still strong with a 0.40-m reflector. It located near by Hercules Cluster M13. The comet’s feature was similar to M13. But the condensation was somewhat stronger than M13, and the comet was much brighter than M13. Comet 73P/Schwassmann-Wachmann 3 has passed the same area just half a year ago. It was impressive that I observed another naked eye comet at the same area.]

So, I confirmed the comet visually, but no rapid brightening occured. It was still fainter than 14.5 mag. Due to the moon light and hazy sky, it was hard to see faint stars. It was uncertain whether it was completely stellar or slightly cometary. After I came back home, I found there must be a 14.5 mag star near by the comet position. But in the DSS image, the 14.5 mag data is actually a blended magnitude of faint two stars. So I judged I observed the comet.]

But I confirmed it again at midnight because the sky became clear with no clouds. The comet is still completely stellar and faint. It is moving among faint background stars in Cygnus, fainter than the limiting magnitude of the GSC. Maybe someone confuse one of the background stars with the comet by mistake? Many people reported it as 14 mag recently. But the comet is definitely fainter, around 15 mag.]
